Abstract: 877,797. Perforating apparatus. NAGAI, K. March 9, 1959, No. 8088/59. Class 31 (2). [Also in Groups XX and XXIV] In film perforating apparatus wherein uniform rotation of a gear-wheel 9, Fig. 1, loose on a shaft 8 is converted into intermittent rotation of a film-forming wheel 21 on the shafts, a ratchet wheel 12 fixed on the shaft is coupled to the wheel 9 by springs and is alternately held and released by a spring-loaded pawl 16, Fig. 6, on a fixed pivot so that the springs are alternately compressed and released to rotate the wheel 12, the release being periodically effected as the wheel 9 rotates by rollers 19 on the wheel 9 engaging the tail of the pawl. The springs 11, Fig. 4, coupling the wheels 9, 12 are mounted in arcuate recesses in the wheel 9 and are engaged by tongues 14 projecting from the face of the wheel 12. As shown, the wheel 12 has four ratchet teeth, the wheel 9 has four rollers 19, and the wheel 9 is driven through a one-to-four reduction gear train by a shaft 2 carrying an eccentric 23 actuating a punch 24 for perforating the film which is fed by the wheel 21.

Abstract: 808,897. Conduits. YOUNG, S. G. June 20, 1955 [March 19, 1954], No. 8145/54. Class 36. A conduit is secured to a box by means of a clamp, at least part of which is formed integrally with the sheet metal from which the box is made. The box 1 (Fig. 1) is formed by bending a sheet-metal blank, one side wall 6 being cut to provide a portion 7 joined to the base by a strip 8. The portion 7 is shaped to provide a semi-tubular central part 10 and lugs 11. A separate member 13 comprises a semi-tubular part 14 having lugs 15, and a flat part 16 shaped to cover the hole in the wall 6, whilst leaving an aperture for the passage of cables into the box. The two clamp parts are secured around a conduit by screws passing through holes 12, 17 in lugs 11, 15. Alternatively, the wall 6 may be omitted, extensions on the adjacent walls being bent around under portion 7 to close this side of the box. The part 16 is then omitted from member 13 (Fig. 3, not shown). The entire clamp may be integral with the box (Fig. 4). Two side walls are formed with extensions 19 which are bent around to form another wall having an aperture 20. A lug 61 projecting from the base 60 is provided with flanges 62 and a recess 64. The lug is bent to the form shown and may be tightened about a conduit by a screw passing through holes 69. Specification 808,898 is referred to.

Title: Contacting device for a dynamo-electric igniting machine driven by a mainspring
IPC: H02K23/66
Filed: 1955-03-22
Abstract: 766,977. Driving dynamos. GLOSSL, H. SCHAFFLER-, and GLOSSL, J. SCHAFFLER-, [trading as SCHAFFLER & CO.]. March 22, 1955 [April 28, 1954], No. 8298/55. Class 35. A spring-driven generator for igniting detonators &c. has a plurality of contacts associated with the drive to ensure that short-circuiting of the ignition circuit occurs only after completion of said circuit during unwinding of the spring and that the circuit remains shorted during the winding up of the spring, a lost motion coupling being included in the contact arrangement. As shown, the inner end of spring 4c is secured to sleeve 4a rotatable on shaft 1a of gear 1 and secured to disc 4 which has a pin 4b in the slot of disc 5 which carries linked contacts 5a, 5b and 5c the first two of which can engage contacts 8, 9 on stationary member 7. Contact 5c engages contact 6a on disc 6 and contact 6b linked with 6a can engage contact 10 which short-circuits the igniters 16 when contacts 9, 10 are engaged by wipers 5b, 6b, this being the position when winding up begins. The spring 4c requires about 1¥ turns during the first ¥ of which disc 4 rotates anti-clockwise without moving disc 5, after which disc 5 is rotated but although contact 9 is then engaged 6b and 10 are still engaged to maintain the short circuit. Only after about a full turn of disc 5 its extension carrying contacts 5c &c. engages the second engaging edge of disc 6 causing contacts 6b and 10 to disengage. On release of the spring, disc 5 remains stationary for the first ¥ turn of wheel 4, then moves clockwise for the second ¥ turn during which the ignition circuit is completed for about four thousandths of a second, followed by the engagement of an extension on disc 5 with one edge of disc 6 driving the latter to cause engagement of contacts 6b, 10.

Title: New cellulose derivatives
Inventor: COUPER JAMES MCGREGOR
IPC: C08B15/06
Filed: 1964-02-28
Abstract: The invention comprises hydroxy difluoramino dialdehyde cellulose and esters thereof. These compounds are formed by reduction of difluoramino dialdehyde cellulose which may be prepared as described in Specification 1,081,081.  A suitable reducing agent is aqueous sodium borohydride.  Esterification may be carried out before or after reduction to form nitrato compounds which have a high energy content; a convenient nitrating agent is a mixture of 100% nitric acid and methylene chloride.  A process is described in which nitration takes place at the 6 position only and also a process in which nitration takes place at the 6 position and at the 2 or 3 position.  The compounds are useful as explosives and constituents of rocket propellants, and have a better thermal stability than the unreduced compounds.ALSO:Propellent compositions contain hydroxy difluoramino dialdehyde cellulose and nitrato compounds thereof (see Division C3).  Reference is made to compositions containing aluminium powder, ammonium perchlorate, nitrocellulose, nitroglycerine, triacetin, and 2-nitrodiphenylamine.

Incrustation and corrosion, preventing.- Apparatus, such as a condenser, which is subjected to physical and chemical conditions liable to produce corrosion, is provided with metallic built-in test pieces which are subsequently inspected, and the nature of the conditions within is deduced from their condition. A tubular test piece 2, which may be of the same material as the parts liable to corrosion, is supported between rubber packing 3 and an insulator 4, and makes contact with a rod 5 by means of a spring 6. Test pieces 11 - - 14 may be built into a surface condenser, pieces 11 and 13 being insulated while 12 and 14 are electrically connected to the tubes 17. If the whole condenser is anodic in relation to the water, pieces 12 and 14 will show signs of anodic attack and pieces 11 and 13 will not. If the condenser is acting as an intermediate electrode, for a current flowing from 15 to 16, test piece 12 will be cathodically encrusted with carbonates and test piece 14 will be anodically attacked. Other conditions of the test pieces indicate corresponding corrosion conditions within the condenser.

Abstract: 1,154,294. Band-splitting circuits. STANDARD TELEPHONES & CABLES Ltd. 22 Feb., 1968, No. 8745/68. Heading H4J. In a circuit, Fig. 1, for splitting an input signal into two signals whose frequency bands are complementary, signals within the pass band of a filter 8 feed directly from input terminal 1 to an output terminal 9. Within this frequency range the differential amplifier 11, 12, is fed with equal and opposite inputs from phase splitter 3 and no signal is fed to output terminal 14. Outside the pass band of filter 8 the input impedance of the filter changes, unbalancing the signals fed to the differential amplifier, so that frequency components in the stop range of filter 8 appear at terminal 14. An alternative circuit is described, Fig. 2 (not shown), having two phase splitters for use with a balanced input and a balanced filter.
